Question #4:
According to the nebular theory, which planet is most likely to be
gaseous rather than rocky?
A. Venus, because it is the warmest planet and so is more likely
to be gaseous
B. Mercury, because planets closer to the solar nebula are more
likely to be made of gas, like the nebula
C. Earth, because the atmosphere consists of nitrogen, oxygen,
and other gases, so it is a gaseous planet
D. Neptune, because as the planets get farther from the solar
nebula, their composition is more icy and gaseous

The Solar nebula was "mostly"
b. hydrogen compounds: ammonia, methane and water
c. heavier elements
d. rocks and minerals
e. hydrogen and helium elements
Which of the following statements is correct?
a. The formation of planets stopped because the solar nebula got cooler
c. The formation of planets stopped because the solar nebula ran out of planetesimals
d. The formation of planets stopped because the solar nebula spinning was slowing down
e. The formation of planets stopped because the young Sun's strong solar wind swept away material not yet accreted onto the planets
